Ostrom is the only energy provider that has the same incentives as you — to use less electricity! With our flat 6 € basic fee, we earn the same from a small flat as from a large house. Therefore, unlike every other energy provider, we genuinely want you to use less electricity.Oh yeah, and we have our top-rated app... and our incredible customer support... and our smart integrations... and our certified green energy...
No, there’s no need to wait! Even if your current contract has up to 12 months remaining, you can sign up early with Ostrom today. Just sign up now, and we’ll take care of the rest — once your existing contract ends according to pre-agreed terms, we will seamlessly switch you to Ostrom.
SimplyFair: Our original transparent tariff for all! Easily add meter readings to track your consumption on our app. Energy prices track the market prices on a monthly basis. In fact, in the last 2 years we’ve already decreased prices seven times!
SimplyDynamic: Our smart-meter compatible tariff! For those customers who already have a smart meter, automatically see your energy consumption on an hourly basis. This means you can take advantage of low prices when the sun shines or the wind blows!Both have all the great features for all Ostrom customers: risk-free monthly cancellable contract, all the features of the Ostrom App (smart home integrations, referrals, perks, CO2 tracking, Ostrom Store, live customer chat & more!)
While energy prices change often, our SimplyFair tariff removes that complexity for our customers. It's the perfect balance between dynamic prices that change hourly and 24-month contracts that keep you locked in to a high price (think households in 2025 still paying 2022 prices).We truly stick to our electricity-at-fair-prices model. This means that unlike our competitors whose prices mostly only go up, we even pass on decreases as well. Since our monthly fixed fee means we do not profit from price increases, increases only happen when market prices change significantly, such as during the energy crisis a few years ago. However since then, we have decreased prices 7 times and only increased once, still achieving a significantly cheaper price over time.
Yes! Both our SimplyFair and SimplyDynamic tariffs do not have the typical 12- or 24-month minimum contract periods like every other provider. We want you to stay because you want to, not because you have to.
